Suppose I have different methods, A, B and C. Suppose further I used these method to select me colour balls. Assume that I need to select three balls using each method. Assume that method A selected 2 reds balls and one green ball. Assume further that, both method B and C selected 3 green balls. Now, I would like to say that method A slect 2 balls different from the choise of method B and C.
Method A selected two balls that are different from the balls selected by both method B and C.
Is my sentence clear and understandable. If not, how can I express my idea in a clear way?
